研究目的: |
本课题的核心目标是解决胃癌TN分期及新辅助治疗疗效预测中的关键问题,并在现有的影像学与人工智能技术基础上进行方法学上的创新与优化。通过引入迁移学习技术,利用预训练模型对高质控影像数据进行微调,显著提升了模型的泛化能力和稳定性,既能充分利用已有的大规模临床影像数据,减少训练时间,又提高了对胃癌TN分期诊断的准确性。同时,本研究通过多模态数据的融合,结合分割、分类等多任务模型,使得新辅助治疗的疗效评估更加精准和全面。模型的应用场景和实际临床效果作为验证的核心点,旨在突破当前临床上诊断准确度不足、疗效评估不准的技术瓶颈,为胃癌患者的治疗方案制定提供更强的辅助支持。 |

Objectives of Study: |
The objective of this study is to address key challenges in TN staging of gastric cancer and prediction of neoadjuvant therapy efficacy, while introducing methodological innovations and optimizations based on existing imaging and artificial intelligence technologies. By incorporating transfer learning techniques and fine-tuning pre-trained models with high-quality controlled imaging data, the model’s generalization ability and stability are significantly enhanced. This approach not only leverages large-scale clinical imaging datasets and reduces training time, but also improves the accuracy of TN staging diagnosis in gastric cancer. Furthermore, through the integration of multimodal data and the use of multitask models combining segmentation and classification, the evaluation of neoadjuvant therapy efficacy becomes more precise and comprehensive. Validation of the model in real-world clinical scenarios serves as a core focus, aiming to overcome current limitations in diagnostic accuracy and treatment response assessment, thereby providing stronger decision-making support for treatment planning in gastric cancer patients. |
